British police said on Wednesday they had arrested a man under anti-terrorism powers at an airport in northern England, an operation the BBC reported was linked to a security swoop last week in Canada.
A 21-year-old man from Bradford was detained at Manchester Airport late on Tuesday and has been taken to a police station in West Yorkshire, a police spokesman said.
The BBC, citing unnamed sources, said the man, believed to be of Pakistani origin, was being questioned in connection with the arrest last week of 17 Muslim men in Canada’s largest counter-terrorism operation.
Several are charged with plotting bombings in major Canadian cities and training militants.
West Yorkshire Police said the BBC report was “speculation” and would not comment further.
The arrest comes less than a week after police in London shot a man during a raid on a house they believed was being used to make a chemical bomb.
